We all want things, want to do things, want to feel things, want to be something. That doesn't change with age. But what does change is our ability to cope with the successes and failures we have.
Youth thinks they know everything, can cope with everything, should be able to have and do everything. However with age comes wisdom. We get to realise our limitations with a more critical eye.
We still aspire to our dreams but know that for the vast majority life gets in the way of those dreams.
Your body, mind and emotions may not be in sync at the moment but when it is you will be in a better position to know if striving for the unusual (if that is your want) is more attainable.
Never give up your dreams and always strive to be the best you you can be. But ultimately life will get in the way and how you deal with that will be what makes you a better person.
